If you slowly kick it past the hard part then give it a big kick it should'nt kick back because you have already past the part where it's just about to fire if you know what I mean
Yeah I had trouble starting my pp 140xr when I first got it.Like the other guys said slowly kick it though until you get past the hard point then give it the KICK of your life if that did'nt get it going then try it again with the throttle open a little bit.
"protaper grips are overrated, look at some of the better ones" Lol,I've got a pair of Scott MX 2 I think that's what they are called they are pretty stiick.
